September is here, which is my favorite time of year to fish the park. The crowds taper off as the kids go back to school and vacationers become less of a presence (after that final Labor Day push,) and the fish tend to turn back on accordingly in the areas that get hammered in July/early August. The yellow bugs (sallies and PMDs) can still surprise you by being a major presence and will continue to be until we start getting colder overnight lows in the near future this month. Continue to think dry flies and dry droppers. There can be some excellent drake hatches all the way through September and into October, so keep an eye out for these big bugs in the air. Caddis, stones, and terrestrials (particularly black beetles and black ants) will also produce in a big way in the late summer/early fall, as will hoppers on warmer days when the sun really activates them. Consider throwing a double dry rig in the Park this time of year, leading with a larger, more buoyant bug like a #10-12 stimulator, #10-12 chubby chernobyl, or #10-12 parachute or foam hopper, and trail with a small black beetle or ant in #16-18, an elk hair caddis in #14-16, or virtually any small emerger or cripple in #16-18 on 14-16" of 5 or 6x tippet. A recent trip to the Wild Basin area found great success on parachute hoppers and small grey comparadun-style dries. Small streamers on the strip or swing on cloudier days can be a lot of fun in the park too, if you're feeling like switching it up. High lakes in the park continue to fish great on beetles, ants, midges, leeches, caddis, and attractor dries like Hippie Stompers and 409s. Remember that fish in the park are usually more picky about a good drag-free drift and a good approach than they are about flies.

The Ultimate Fly Fishing Report
Casting a fly in a tranquil mountain stream, feeling the tug on the line, and holding a beautiful rainbow trout makes us feel alive and intensely connected with nature. Fly fishing is our way of life and we are blessed with hundreds of nearby rivers and streams just a short distance away from Boulder. From the swift spring waters of the Clear Creek to the meandering bends of the South Platte, it's critical to consider fishing conditions in advance and prepare accordingly. We rely on our experienced guides who venture into the wild to let us know which rivers favor fly fishing, where fish are biting, and which fly patterns are most effective. Planning a successful fishing trip also requires knowledge of stream flows at various river points and an accurate weather forecast for a given destination. At Rocky Mountain Anglers, we are dedicated to providing all avid anglers with detailed and timely information about hatches, water, and weather conditions. So before you head out the door on your next fishing adventure, visit our web site to find valuable information that will prepare you for a successful trip. Have fun chasing after your next trophy trout and enjoy nature's beauty!The Rocky Mountain Anglers Crew
